Past Samsung Pro drives were MLC drives with higher endurance, but they "downgraded" that with 980 Pro.Dell Precision T1600 Service Manual Regulatory Model: D09M Regulatory Type: D09M001 970 EVO Plus and 980 Pro are both TLC so they have similar endurance. (980 Pro has PCIe4 which will not be useful in this system. Samsung 970 EVO Plus is a bit cheaper than 980 Pro and otherwise pretty similar. Otherwise, just swapping out the drive is a good idea. If the disk controller mode in the BIOS is set to RAID mode (which is the default) then you can use this procedure to switch to AHCI mode.
#Dell precision 490 diagnostic lights 1 and 2 driver
That will switch the disk controller driver in use which may (or may not) help work around this problem. You can try switching from RAID mode to AHCI mode or vice versa. (It is suddenly unable to read anything off of the disk so basically the OS grinds to a halt.) If the mouse is also locked up I'd be more suspect of the RAM.Īnyway. Just thought I'd post in case anyone has any ideas before I get my hands on an alternate ssd to test with.Ĭlick to expand.Does the mouse cursor still move when the system is locked up? That'd be consistent with a drive issue. Seems like it might be ssd/storage controller related due to the blinking drive light most of the time it freezes, but not sure if it's something with the board controller hardware or the 950 pro ssd since I don't have another one on hand to test with yet.

I don't think I can get a like 950 pro ssd any more, so if I can't think of anything else I suppose I'll grab a 1 TB 980, do a fresh install and if that's good, restore a windows backup image to it and see if the problem continues. Tried reseating battery, memory, and ssd and didn't have a problem for 4 days, but then today it froze twice. It first happened only twice when running a windows defender full scan, then no problems for a few months, but now crashed when doing random things (just browsing the web with two browsers open, running windows update, and even shutting down with the blue shutting down screen hanging and the wheel spinning for 15 minutes and the hard drive light blinking but never actually shutting down.)Īnyone seen any odd behavior with driver updates and the 950 pro ssd in this machine this year? A scan of the drive from windows shows no errors following a power cycle, and unfortunately after rebooting there is nothing relating to the hang event that I can find logged in event viewer. Samsung Magician shows no smart errors on the drive. I have a 512 GB samsung 950 pro nvme ssd as the boot drive. Often the hard drive light is blinking while it's frozen up in a seemingly constant blinking pattern. Only thing I can seem to do is hold the power button down to power off and then power on. My 7710 started having an issue where it just freezes up - can't click on any buttons, start menu, or ctrl+alt+delete.
